This particular directive related to Boeing 737 aircraft. By repealing it, CASA is effectively saying the safety issue has been resolved, superseded by newer rules, or is no longer considered a risk requiring mandatory action.\n\n**Who is affected**\nAirlines and operators flying Boeing 737 aircraft in Australia who were previously required to comply with AD/B737/87 Amdt 2."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-019-15-repeal-of-airworthiness-directive","history":"/api/acts/casa-adcx-019-15-repeal-of-airworthiness-directive/history","analysis":"/api/acts/casa-adcx-019-15-repeal-of-airworthiness-directive/analysis","conflicts":"/api/acts/casa-adcx-019-15-repeal-of-airworthiness-directive/conflicts","importantCases":"/api/acts/casa-adcx-019-15-repeal-of-airworthiness-directive/important-cases","documents":"/api/acts/casa-adcx-019-15-repeal-of-airworthiness-directive/documents"}}
